Later today I’ll lose consciousness for a few hours to rest and repair. There’s a good chance you will, too. Yet as ubiquitous as sleep is, we know very little about which parts of the brain are fundamental to staying awake.
Thanks to a recent experiment that stimulated the brains of anaesthetised macaques, we have a clearer idea of just which neurological structures might be primarily responsible for switching us on each day.
Facebook boss Mark Zuckerberg has called for more regulation of harmful online content, saying it was not for companies like his to decide what counts as legitimate free speech.
Citing China, Mr Zuckerberg also warned excessive control risked stifling individual expression.
He was speaking at the Munich Security Conference in Germany.
Amberd (Armenian: Ամբերդ) is a 10th-century fortress located 2,300 meters (7,500 ft) above sea level, on the slopes of Mount Aragats at the confluence of the Arkashen and Amberd rivers in the province of Aragatsotn, Armenia. The name translates to “fortress in the clouds” in Armenian. It is also the name incorrectly attributed to Vahramashen Church, the 11th-century Armenian church near the castle. The village of Byurakan is 6.4 kilometres (4.0 mi) from the site of Amberd.
The site started as a Stone Age settlement. During the Bronze Age and Urartian periods, a fortress had been built that is now obsolete. Some sources say that Amberd used to be a summer residence for kings. The castle of Amberd and some sections of walls were constructed in the 7th century as a possession of the noble House of Kamsarakan.
Four centuries later the fortress and surrounding lands were purchased by the House of Pahlavuni and rebuilt by Prince Vahram Pahlavouni, as is recorded in the manuscripts of Grigor Magistros Pahlavuni. Vahram built the Church of Surb Astvatsatsin in 1026, fortified the complex with thicker stone walls, and added three bastions along the ridge of the Arkhashen canyon. Despite being unusual for a military installation, a bath house was built in the same period and has remained moderately intact along with the water supply system.
#Amberd was invaded in the 1070s by the Seljuq Turks who turned it into a military base. In 1197, a joint-army of Armenians and Georgians led by General Zakare Zakarian liberated the fortress. Under Zakarian control during the 12th and 13th centuries, the walls were structurally reinforced and the castle and outer buildings were renovated.
Microsoft co-founder Bill Gates has been working to improve the state of global health through his nonprofit foundation for 20 years, and today he told the nation’s premier scientific gathering that advances in artificial intelligence and gene editing could accelerate those improvements exponentially in the years ahead.
“We have an opportunity with the advance of tools like artificial intelligence and gene-based editing technologies to build this new generation of health solutions so that they are available to everyone on the planet. And I’m very excited about this,” Gates said in Seattle during a keynote address at the annual meeting of the American Association for the Advancement of Science.
Such tools promise to have a dramatic impact on several of the biggest challenges on the agenda for the Bill & Melinda Gates Foundation, created by the tech guru and his wife in 2000.
Billionaire tech entrepreneur Elon Musk says if people are negative about the present, then they aren’t reading enough history. Bill Gates and Warren Buffett also agree this is the best time to be alive.
Coronvirus fears are being raised in earnings calls throughout different sectors as Wall Street looks for any effects from the virus spreading within and outside of China, which should lead to a lot of talk on what could be the busiest single day of the earnings season.
Nearly 10% of the S&P 500 index SPX, +0.18%, 46 components, are scheduled to report on Wednesday, along with four members of the blue-chip Dow Jones Industrial Average DJIA, −0.09% — Boeing Co. BA, −0.68%, Dow Inc. DOW, +0.68%, McDonald’s Corp. MCD, −0.15% and Microsoft Corp. MSFT, +0.89%.
The company on that list most linked to coronavirus fears is McDonald’s, which has had to temporarily shut down some of its stores in China due to fears about the outbreak. During the SARS crisis in the early 2000s, there was a “pronounced but relatively short-lived” impact on restaurant sales in the Greater China region, according to Bernstein analyst Sara Senatore. China accounts for only 2% of McDonald’s earnings and the company has only closed about 1% of its China stores so far, so expect executives to play down any effects when they report before the bell Wednesday.
